Using Basic Algebra

[Mobark]

So I'm trying to calculate a variable cost into one of my cells. Below is my description, can I make a formula to achieve my desired results.

Target (T) = 100 (Defined #)
# of samples (S) from one unit = 10 (Defined #)
# of units required (U) = 10 (Variable)

S*U=T

I will always have the Target(T) and the # of samples(S) from a unit, I would like to input a formula which always gets me the units (U) required when I change either of the other two numbers.

THanks for your help in advance.

Ummm...so even more basic algebra, just flip the =T*S/U. Whoops...Figured it out, thanks to readers, sorry for wasting time.
